Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 An embodiment of this utility model is provided: a centrifugal air compressor with a shock-absorbing mounting structure, including a base 1 and a left compression housing 8. The left compression housing 8 is installed on the left side of the top of the base 1, the middle compression housing 26 is installed at the center of the top of the base 1, and the right compression housing 18 is installed on the right side of the top of the base 1. A transverse chamber 2 is provided inside the base 1, and a transverse shaft 3 is movably connected between the two sides inside the transverse chamber 2. Three sets of bidirectional threads 24 are provided on the outside of the transverse shaft 3, and threaded blocks 4 are respectively sleeved on both sides of the surface of the bidirectional threads 24. A plate 7 is fixed at the top of the threaded block 4, and a sound-absorbing pad 25 is fixed on the side of the plate 7. A layer of sponge pad 6 is fixed on the upper surface of the base 1, and a handle 5 is movably connected to the left side inside the base 1.

[0025] A conveying pipe 27 is installed behind the left compression housing 8 and the middle compression housing 26. A left pipe 9 is installed on the left side behind the left compression housing 8, and a diffuser 10 is installed above the left pipe 9. A left valve 11 is installed in front of the diffuser 10. A middle pipe 13 is installed at the center of the front end of the middle compression housing 26, and a diffuser 2 14 is installed behind the top end of the middle pipe 13. A right valve 16 is installed in front of the diffuser 2 14. Impellers 12 are installed inside the diffuser 10 and the diffuser 2 14 respectively. A right pipe 17 is installed between the diffuser 2 14 and the right compression housing 18.

[0026] The plate 7 is attached to both sides of the left compression housing 8, the middle compression housing 26 and the right compression housing 18. The plate 7 and the threaded block 4 are on the same vertical plane. The inner wall of the threaded block 4 matches the bidirectional thread 24. The left compression housing 8, the middle compression housing 26 and the right compression housing 18 are placed on the sponge pad 6.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the left compression housing 8, the middle compression housing 26, and the right compression housing 18 are placed on the sponge pad 6 at the top of the base 1. Rotating the handle 5 on the left allows the horizontal shaft 3 to be rotated in the transverse chamber 2. In conjunction with the three sets of bidirectional threads 24 on the surface of the horizontal shaft 3, the corresponding two sets of threaded blocks 4 can be pushed toward the center, forcing the plate 7 at the top of the device to adhere to both sides of the surfaces of the left compression housing 8, the middle compression housing 26, and the right compression housing 18, thus avoiding excessive vibration and noise during device operation and preventing vibration from being transmitted to the ground.

[0028] Two sets of limiting blocks 15 are fixed at the rear of the top of the left compression housing 8, the front of the top of the middle compression housing 26, and the rear of the top of the right compression housing 18, respectively. Two sets of collars 29 are movably connected between the interior of the limiting blocks 15. Screw holes 30 are provided on the interior of both sides of the collars 29, and fastening bolts 31 are threaded between the front and rear of the screw holes 30. Holes 32 are longitudinally provided on the surface of the limiting blocks 15, and limiting bolts 28 are threaded in the holes 32. The collars 29 are symmetrically sleeved on the front and rear ends of the left pipe 9, the middle pipe 13, and the right pipe 17. The rear of the limiting bolts 28 abuts against both sides of the collars 29 in the limiting blocks 15, and both sides of the collars 29 are embedded in the limiting blocks 15.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, collars 29 are fitted onto the front and rear surfaces of the left pipe 9, the middle pipe 13 and the right pipe 17 respectively. After the screw holes 30 are locked with fastening bolts 31 on both sides, the collars 29 are inserted into the grooves of the limiting block 15 on both sides after being brought together. Then, the hole 32 is selected and the limiting bolt 28 is screwed in to tighten it, so that each connecting pipe can be clamped and fixed.

[0030] A hose 36 is installed on the lower right corner of the outside of the right compression housing 18, and a box 19 is fixed to the right side of the hose 36. An air outlet pipe 20 is installed on the right side of the box 19. The inside of the box 19 is filled with filler 35. A cylinder 23 is installed on the right side of the top of the base 1, and a slider 22 is fixed to the top of the piston rod of the cylinder 23. A groove 21 is provided on the lower surface of the outside of the box 19. A frame 34 is fixed to the outside of the left side of the hose 36. Two sets of connecting pieces 33 are fixed to the surface of the left side of the box 19. The left side of the connecting piece 33 is movably connected to the frame 34. The slider 22 is embedded in the groove 21.

[0031] Specifically, such as Figure 1 and Figure 4As shown, when the left valve 11 is opened, the airflow is drawn into the diffuser 10 by the impeller 12 inside, enters the left compression housing 8 through the left pipe 9, flows to the middle compression housing 26 through the delivery pipe 27, enters the diffuser 2 14 again through the middle pipe 13, is pressurized again by the impeller 12, and finally enters the right compression housing 18 through the right pipe 17 for discharge. When the high-pressure gas leaves the compressor body, it flows into the box 19 through the hose 36, is adsorbed and filtered by the packing material 35 made of activated carbon, and is then discharged from the outlet pipe 20. At the same time, the cylinder 23 is opened and the slider 22 embedded in the slide groove 21 pushes the box 19 to shake, preventing impurities from clogging the mesh.

[0032] Working Principle: When using this utility model, firstly, place the left compression housing 8, the middle compression housing 26, and the right compression housing 18 on the sponge pad 6 at the top of the base 1. Rotating the left handle 5 allows the horizontal shaft 3 to rotate in the transverse chamber 2. The three sets of bidirectional threads 24 on the surface of the horizontal shaft 3 can push the corresponding two sets of threaded blocks 4 towards the center, forcing the top plate 7 to adhere to both sides of the surfaces of the left compression housing 8, the middle compression housing 26, and the right compression housing 18, thus preventing excessive vibration and noise during operation. Then, sleeve rings 29 are fitted along the front and rear surfaces of the left pipe 9, the middle pipe 13, and the right pipe 17. After locking the screw holes 30 on both sides with fastening bolts 31, insert the sleeve rings 29 into the grooves of the limiting blocks 15 along their closed sides. Finally, select the hole 32 and screw in the limiting bolt. 28 is pressed tightly to secure each connecting pipe. During operation, the left valve 11 is opened, and the airflow is drawn into the diffuser 10 by the impeller 12 inside. It then enters the left compression housing 8 through the left pipe 9, flows to the middle compression housing 26 through the delivery pipe 27, and enters the diffuser 2 14 through the middle pipe 13. It is then pressurized again by the impeller 12 and finally enters the right compression housing 18 through the right pipe 17 for discharge. When the high-pressure gas leaves the compressor body, it flows into the box 19 through the hose 36 and is adsorbed and filtered by the packing material 35 made of activated carbon. Then it is discharged from the outlet pipe 20. At the same time, the cylinder 23 is opened and the slider 22 embedded in the slide groove 21 pushes the box 19 to shake. The left side is supported by the connecting piece 33 installed in the frame 34, and the logarithmic output gas is filtered to prevent clogging.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
